Yes, a NASA study published in August 2024 suggests that Mars has an underground ocean of liquid water

Size 

The water is enough to cover the entire planet to a depth of 1.6 kilometers

Location 

The water is located 7.2 to 12.4 miles below the surface, trapped in fractured igneous rocks

Discovery 

The discovery was made by analyzing seismic wave data from NASA’s InSight lander, which touched down in 2018

Significance 

The discovery indicates that Mars has a much larger amount of water than previously thought, and that the conditions underground could support microbial life.

The first evidence of water on Mars was found in 2004 by NASA’s Mars Odyssey orbiter. But now NASA has found an ocean full of water. Yes, you read it right. This find, based on data from a retired NASA mission, opens up new possibilities for understanding the planet’s history and the potential for life

Our cosmic neighbour Mars, the mysterious Red Planet, has long intrigued scientists and dreamers alike with its barren, rusty landscapes. Now beneath the dusty plains of Mars, there is a vast reservoir of water. This reservoir is believed to be trapped in the tiny cracks. NASA says that the water is hidden between tiny cracks and pores of rock. However there is a problem, we can’t start drilling anytime soon. The data from NASA’s Insight lander indicate the water is hidden between 11.5 and 20 kilometres beneath the surface. However, the amount of water contained in this mid-crust zone is huge. It could cover the entire planet to a depth of 1.6 kilometres

Understanding the Martian water cycle is critical for understanding the evolution of the climate, surface and interior,” said Vashan Wright, Assistant Professor, at the University of California San Diego’s Scripps Institute of Oceanography. His detailed findings will appear this week in the journal Proceedings of the National Academy of Sciences

MARS’ WET PAST: NEW CLUES FROM UNDERGROUND SEA

The recent findings of NASA are based on computer modelling and seismic measurements from NASA’s InSight lander. Scientists analysed the data collected from the lander which landed on Mars in 2018. The lander carried a seismometer which was designed to detect Mars quakes (similar to earthquakes). The aim was to understand the geology of the plant. The spacecraft detected more than 1,300 marsquakes before shutting down two years ago.

LIFE ON MARS? UNDERGROUND RESERVOIR SPARKS HOPE

This new evidence suggests that instead of escaping entirely, much of Mars’ water may have simply moved underground, where it remains locked away. This discovery could be crucial, as accessing this water would be vital for sustaining human missions to Mars. Moreover, the presence of liquid water raises the exciting possibility that Mars could have once harboured life-and who knows, life in some form might be hidden under the Martian surface

Was there an ocean found on Mars?

Enough water to cover the surface of Mars in an ocean between one and two kilometers (0.62 and 1.24 miles) deep has been discovered within the crust of the Red Planet by NASA’s InSight mission. InSight, which was a stationary lander during operation, touched down in the Elysium Planitia region on Mars in November 2018

Water is necessary for life as we know it,” study co-author Michael Manga, a professor of earth and planetary science at UC Berkeley, said in a statement. “I don’t see why [the underground reservoir] is not a habitable environment. It’s certainly true on Earth — deep, deep mines host life, the bottom of the ocean hosts life.”

We haven’t found any evidence for life on Mars, but at least we have identified a place that should, in principle, be able to sustain life,” Manga added

Currently, reaching the secret ocean is comfortably outside humanity’s technical abilities (the deepest hole ever dug on Earth, the Kola Superdeep Borehole, only burrows 7.6 miles into our planet’s surface) yet it’s not the only place scientists are searching for life on Mars. 

In fact, samples of Mars’ dust, and even evidence of ancient life, could have already been collected by the Perseverance rover, which has been exploring the surface of Jezero crater to collect geological samples since 2021. 

NASA initially planned for a sample retrieval mission to launch sometime in 2026, but this date has since been delayed until 2040 due to budget concerns. The agency is currently soliciting proposals from private companies to speed up the mission timeline.

Vashan said that the upper layer of Mars, i.e. the crust, creates such an environment at such a depth that liquid water can accumulate in it. Whereas in shallow depths it solidifies into ice. This study by Vasan and his colleagues has recently been published in the Proceedings of the National Academy of Scienc

Insight lander’s ability to read seismic waves revealed

Vashan’s fellow researcher Michael Manga said that on Earth too we have discovered microorganisms at such depths. Where there is water saturation. There is no energy source either. But the Earth is warm enough for life to flourish. NASA’s InSight lander landed on the surface of Mars in 2018. so that we can study inside

This lander helped in mapping the inner layers of Mars with its seismic waves. Vashan said that after studying this data, he has concluded that there is a large amount of water stored under Mars. When these waves pass through any object, they undergo changes.

If all the water is taken out, the entire planet will become one big ocean.

When waves pass through stone, they behave differently. When it passes through water, it behaves differently. It becomes clear where the cracks are. By studying these waves, Vashan and his team found out how much water is present where and at what depth. In this manner, large sources of water, oil and gas are discovered on Earth. 

There was a time when Mars was both warm and wet.

Right now the surface of Mars is cold. It is desert. But sometimes it was hot and wet. But this changed 300 crore years ago. The study shows that the water present on Mars did not disappear in space. Rather, it got filtered through the crust layer and got accumulated inside. There were rivers and lakes of water on early Mars. Sagar might also have been there. This discovery has raised hopes that a long-term human colony can be established on Mars with the help of water.

Does it rain on Mars?

Mars is drier and colder than Earth, and in consequence dust raised by these winds tends to remain in the atmosphere longer than on Earth as there is no precipitation to wash it out (excepting CO₂ snowfall

How long is a day on Mars?

1d 0h 37mMars/Length of day

Mars is a planet with a very similar daily cycle to the Earth. Its sidereal day is 24 hours, 37 minutes and 22 seconds, and its solar day 24 hours, 39 minutes and 35 seconds. A Martian day (referred to as “sol”) is therefore approximately 40 minutes longer than a day on Earth.

What are 5 facts about Mars?

Impress your family and friends with these 20 fascinating and fun facts about Mars.

• Mars is also known as the Red Planet. … 
• Mars is named after the Roman god of war.
• Mars has 2 moons called Deimos and Phobos. … 
• Mars is the 4th planet from the sun. … 
• Mars is smaller than Earth with a diameter of 4217 miles.

Could Martians have come to earth 🌍 long ago

Yes, it’s possible that life on Earth originated on Mars and was brought here by a meteorite. This theory is based on a few factors, including

Mars was more hospitable 

Some researchers believe that Mars was a better place for life to start than Earth billions of years ago. For example, Mars may have had oxidizing conditions earlier than Earth, which could have helped organic compounds form life

Meteorite evidence 

A Martian meteorite found on Earth contains evidence of past water movement and carbon-rich spheres that may have been formed by biotic activity

Molybdenum 

Biochemist Steven Benner says that oxidized molybdenum was available on Mars, but not on Earth when life first began. This form of molybdenum is important for helping organic compounds form life

Is it possible that Mars had life before Earth?

At least two-thirds of Mars’ surface is more than 3.5 billion years old, and it could have been habitable 4.48 billion years ago, 500 million years before the earliest known Earth lifeforms; Mars may thus hold the best record of the prebiotic conditions leading to life, even if life does not or has never existed there.
